Smart city heterogeneous data sharing method based on meta model

Abstract

The invention discloses a smart city heterogeneous data sharing method based on a meta model. The smart city heterogeneous data sharing method based on the meta model comprises the first step of establishing a city data meta model modeling frame according to the MOF meta modeling theory, the second step of establishing a city data meta model universal element set according to city data characteristics and description requirements, the third step of developing a data meta model special element set according to city data basic classification and a special element set expansion mode, the fourth step of forming a meta model universal element set and special element set formalization method on the basis of XML template modeling, the fifth step of achieving network directory services and data services and establishing an open city data meta model registering and managing platform, and the sixth step of designing a city data fine granularity discovery interface and obtaining data according to practical application requirements of users. According to the smart city heterogeneous data sharing method based on the meta model, an open and standard city heterogeneous data sharing solution is provided for users, support is provided for city heterogeneous data online access, follow-up processing and collaborative application, and the method is efficient, practical and reliable during city heterogeneous data sharing.

Description

[0001] technical field [0002] The invention belongs to the technical field of smart city information sharing and interoperability, and relates to a method for sharing urban heterogeneous data, in particular to a metamodel-based smart city heterogeneous data sharing method. [0003] Background technique [0004] With the continuous development of cities, urban problems such as population expansion, traffic congestion, environmental pollution, and energy shortages continue to increase, and the concept of smart cities has emerged as the times require. Smart city is based on the scientific concept of urban development, using a new generation of information technology, based on the comprehensive perception and interconnection of ubiquitous information, to realize the seamless connection and collaborative linkage between people, things and urban functional systems. Adaptation and self-optimization, so as to make intelligent responses to various urban needs such as people's live...

Problems solved by technology

[0011] 1) There is a lack of top-level design and multi-faceted detailed descriptions of multiple types of data. Various data tend to form information islands, and various data sources cannot be fully understood and discovered;

[0012] 2) There is a lack of a cross-platform, universal data discovery and acquisition interface, which cannot satisfy user
